Modellierung und kartographische Visualisierung von Geodaten mit XML-basierten Sprachen     

Brigitte Mathiak  Andreas Kupfer und Karl Neumann 《Informatik - Forschung und Entwicklung》2005,20(1-2):24-32

Zusammenfassung Mit den XML-basierten Sprachen GML, XSLT und SVG lassen sich Geodaten nicht nur anwendungsorientiert modellieren, sondern auch karten?hnlich visualisieren. In dieser Fallstudie zeigen wir das, indem wir realistische Geodatenbest?nde der Landesvermessungs?mter zun?chst mit der Geography Markup Language (GML) nachmodellieren. So mit GML strukturierte Daten werden dann mit der Extensible Stylesheet Language for Transformation (XSLT) auf Elemente der Sprache Scalable Vector Graphics (SVG) abgebildet. Dabei wird der Prozess der kartografischen Visualisierung durch XSLT-Konstrukte modelliert und auch gleichzeitig implementiert. Als Ergebnis erhalten wir Grafiken, die den entsprechenden Karten der Landes?mter zumindest nicht un?hnlich sind.

Using the XML-based languages GML, XSLT and SVG, we modeled German geo data and also visualized it in map-like graphics. This case study shows the feasibility of that approach, by modelling the data with the Geography Markup Language (GML). Then, the GML-structured data is mapped with the Extensible Stylesheet Language for Transformation (XSLT) to elements of the language Scalable Vector Graphics (SVG). The process of cartographical visualization is thus modelled through XSLT-constructs and at same time also implemented. The results are graphics, which share close ressemblance to the corresponding maps of the official offices.

我国促进大数据发展政策工具选择体系结构及其优化策略研究     

李樵 《图书情报工作》2018,62(11):5-15

[目的/意义]探究我国为实现促进大数据发展的政策目标而构建的政策工具选择体系结构,揭示大数据政策工具选择中存在的问题,为优化我国促进大数据发展政策工具选择提供建议。[方法/过程]构建由63项聚焦大数据发展的政策文本构成的政策样本集,运用内容分析法,对样本集中包含的政策工具进行编码。建立包含基础资源维度、技术维度和领域维度的政策工具选择三维分析框架,通过编码映射,建立其与政策工具编码的关联。从领域维度,使用层次聚类分析法,对样本政策文本进行聚类分析。[结果/结论]政策工具编码分析结果显示,我国大数据政策工具选择中存在缺乏长期规划,政策及政策工具协同不足,政策工具选择欠丰富;政策工具选择结构失衡;需求表达模糊,难以定位关键政策及政策工具等问题。应加强战略规划和发展理念指引,重视政策及政策工具协同,规避公共风险,构建需求驱动和问题导向的政策工具选择体系结构,创新设计与应用关键政策工具。  相似文献   

UNIMARC Format Relevance: Maintenance or Replacement?     

Rosa Maria Galvão 《Cataloging & classification quarterly》2018,56(1):62-82

This article presents an empirical study focused on a qualitative analysis of the UNIMARC format. An analysis of the structural quality of the data provided by the format is evaluated to determine its current suitability for meeting the requirements and trends in data architecture for the information network and the Semantic Web. Driven by a set of quality characteristics that identify weaknesses in the data schema that cannot be bridged by simply converting data to MARC XML or RDF/XML, we conclude that the UNIMARC format is not compliant with the current metadata schema desiderata and must be replaced.  相似文献   

Assessing the Benefits of Content Notes Enhancements for Digital Audio Resources     

Laura N. Kirkland  Jean Wald 《Cataloging & classification quarterly》2018,56(4):287-297

Our library has previously investigated the potential impact the addition of contents notes on circulation. In a subsequent study, we found contents notes were the second metadata element most heavily linked to circulation (title was first). Since there has been a marked decline in the use of print resources at our library and a corresponding increase in digital resources, we wanted to know if the addition of contents notes to records for online streaming audio files would result in a similar increase in usage. After enhancing the records, we tracked usage for a period of three months.  相似文献   

The Changing Research Data Landscape and the Experiences of Ethics Review Board Chairs: Implications for Library Practice and Partnerships     

Brian Jackson 《The Journal of Academic Librarianship》2018,44(5):603-612

Academic libraries have to a large extent taken the lead in facilitating new approaches to research data management, but changes to the research data landscape have had an impact on numerous areas of academic work, including ethics review. Using interpretive phenomenological analysis of interviews with chairs of Canadian research ethics boards, this study explores how ethics review boards have experienced changes to data policy and related technologies in order to describe the ethical implications of new approaches to data management and to explore ways in which the library, ethics review boards, and other campus partners might harmonize efforts to support emerging data practices. While ethics review boards in Canada are keenly aware of open data policies, data publishing in practice is still nascent. There is uncertainty about the adoption of changing technologies for research and their impacts on privacy protection. Where responsibility lies for addressing these uncertainties is often unclear. Academic libraries and research ethics boards are well-suited to engage in mutual knowledge transfer and to integrate data management planning and ethics review processes. Institutional-level oversight that includes all campus departments impacted by changes to the research data landscape may facilitate improved communication and reduce role ambiguity.  相似文献
